Here's an article by the very clever and influential Norman Doidge. He is a neuroscientist who argues that our brains are capable of changing based on how we use them. He is a leader in the field of NEURO-PLASTICITY. This sounds complicated and science but what is basically means is that we can build new connections and strengthen existing networks between neurons if we use our brain in specific ways. We can train ourselves to think and learn better. We can actually change the biological structure of our brain tissue! That's actually pretty amazing!
